This isn't easy to answer because 'middle layer' is hard to pin point. From the outside front to the back, this is the order, Conjunctiva, cornea, aqueous humor, pupil (with the iris at both sides), lens, vitreous humor, retina, and then the optic nerve.
The uvea is the middle vascular layer of the eye. It contains the iris, ciliary body and chorid.
The sensory tunic is the retina of the eye but has various components such as rodes, cones, optic disc, macula lutea, and the fovea centralis.
Vascular Layer
Uvea
choroid.. essentially vascular layer
retina
melanin
Pigment cells (melanocytes) are found in the basal layer of the epidermis.
Which layer of cells contains vascular tissue
uveitis
The middle layer of the atmosphere is the Mesosphere.

The vascular layer of the eye is the middle layer. It is also called the uvea. The vascular contains the iris and lens. The iris contains the light levels inside the eye.
The dermis is the vascular layer of your skin.
Choroidea!
The choroid forms the bulk of the heavily pigmented vascular layer.
Vascular tunic. This is the middle layer of the eye and is made up of the choroid, the ciliary body, and the iris. Altogether, these structures are called the uvea
This is the middle layer of the eyeball and it is composed of the choroid, ciliary body and iris.
Vascular Coat or Uvea is the middle part of the wall of the eye. Uvea has a rich supply of blood vessels that provides nutrients of the eye.
truely,no layer of the hair has pigment. if i didnt help try google. good luck,soldier. :) :) :) :) :) :) :)
Reticular Layer
impestro
There is no major difference, its just that dark eyes have Iris with a dark pigment layer. Its not that the other colorful eyes don't have the pigment layer, they do but because the color of pigment layer differ therefore color of eye differ. Blue eyes don't have pigment.
